Port 8090 not working after installation

After installing CyberPanel, port 8090 is not working. I know that the port is open. Also, if I go to the IP address URL, it shows a 404 error (CyberPanel is running). During the panel installation, an error occurred and it was interrupted. I fixed the error manually, but I couldn’t proceed with the installation (it indicates that the panel is already installed). When I enter the command “systemctl status lscpd”, it returns “Unit lscpd.service could not be found.” I tried to install it manually, but still couldn’t succeed.

Try checking if your Port has changed from 8090
/usr/local/lscp/conf/bind.conf
If it has, change it back to 8090

Then do systemctl restart lscpd

To file:
/usr/local/lscp/conf/bind.conf
add:
*:YOUR_PORT
and in any file in
/usr/local/CyberCP/
change hard-coded port 8090 to YOUR_PORT:
grep 8090 /usr/local/CyberCP -rl |grep -v “.php\|.css\|.js\|.pem\|.html\|.png\|site-packages”|xargs -i sed -i ‘s/8090/YOUR_PORT/’
systemctl restart lscpd

root@tokishu:/# systemctl restart lscpd
Failed to restart lscpd.service: Unit lscpd.service not found.
